Unable to Enable Windows Sandbox Due to Component Store Corruption

Danny 0

Attempted to enable Windows Sandbox but encountered the error: "An error has occurred. Not all of the features were successfully changed." Steps taken include:

Using the NetFXRepair tool with no success.

Rebooting the system did not resolve the issue.

Running a PowerShell command resulted in "The component store has been corrupted."

Executed sfc /scannow and DISM commands, but these commands did not work despite being entered correctly.

Hyper-V is enabled, and reinstallation was attempted.

Any guidance on resolving this issue would be appreciated.

Hello. When DISM failed, did it mention source files could not be found (0x800f081f)? Is this a clean Windows 11 install, or did it start as Windows 10 and upgrade?

Windows optional feature enablement relies on the Component-Based Servicing (CBS) stack and Windows Component Store (WinSxS). If corruption is present and unrecoverable by DISM, the issue is system-wide and not limited to Windows Sandbox.

Thanks for the update, you’re likely dealing with leftover corruption from the upgrade. That’s why DISM couldn’t fix things, it ran but couldn’t process the repairs properly, likely because some key Windows files are damaged or missing.

Download the exact same edition of Windows 11 you’re running (e.g., Home, Single Language) using the Media Creation Tool: https://www.microsoft.com/software-download/windows11

Mount the ISO, run setup.exe from it, and perform an in-place upgrade repair. Choose:

Keep personal files and apps

Do not boot from the USB. Must be launched from within Windows.

This rebuilds the Component Store from scratch and re-registers all feature payloads.

Hopefully this works for you.

Hello Danny, I am Henry and I want to share my insight regarding your issue.

Based on your confirmation that the system was upgraded from Windows 10 to 11, we can identify the source of the problem. This type of upgrade can sometimes leave behind corrupted or mismatched system files, which explains why standard repair tools like sfc and DISM are failing.

The reliable way to fix this is to perform an in-place upgrade (repair install), which will rebuild your Windows component store without deleting your files or applications.

Download the Windows 11 ISO:
- Go to the official Microsoft Software Download page for Windows 11.
- Under the "Download Windows 11 Disk Image (ISO)" section, select "Windows 11 (multi-edition ISO)" and click Download.
Mount the ISO File:
- Once downloaded, find the ISO file in your Downloads folder.
- Right-click the ISO file and select Mount. This will create a new virtual drive (like D: or E:) in File Explorer.
Run the Setup:
- Open the new virtual drive and double-click the setup.exe file to begin the installation.
- Important: You must run this from within your current Windows session. Do not boot your computer from it.
Install Windows:
- Follow the on-screen prompts. When you reach the "Ready to install" screen, you MUST ensure that it says: "Keep personal files and apps"
- If it doesn't offer to keep your files and apps, stop the process, as there may be an edition mismatch. Otherwise, click Install.

Your computer will restart several times. This process can take a while, but once it's finished, the component store will be fully repaired. You can then go to Turn Windows features on or off and enable Windows Sandbox successfully.

I hope you’ll give my recommendation a try and let me know how it goes.
